Thanks. My sister went to see these. Each has it's own face, not two are alike.
"Each has it's own face, not two are alike."
Actually there are six different faces on the statues repeated over and over. No two identical faces appear side by side so it gives the illusion that all the soldiers are unique individuals. I studied the topic a few years after the discovery. I is quite amasing.
Previous to this burial Chinese kings buried all their possessions including their servants when they died.
